Abstract

The prototype of a K̄ nuclear cluster, K-pp, has been investigated using effective K̄N potentials based on chiral SU(3) dynamics. Variational calculation shows a bound state solution with shallow binding energy B(K-pp) = 20 ± 3 MeV and broad mesonic decay width Γ(K̄NN → π YN) = 40-70 MeV. The K̄N(I = 0) pair in the K-pp system exhibits a similar structure as the Λ(1405). We have also estimated the dispersive correction, p-wave K̄N interaction, and two-nucleon absorption width.
